Air compressors and their main types

The modern market offers a huge selectioncompressor equipment. It is designed for compressed air, which can be used to operate pneumatic tools and for other purposes. Devices different operation principle, dimensions, specifications, and other parameters. Before you buy an air compressor, you need to decide on his views. All variety of devices can be divided into screw and piston.

Features screw compressors

Devices of this type consist of a frame and 2Rotors: master and slave. They are connected with each other. First by a belt or a reduction gear connected to the electric motor. Rotors perform rotational movements in opposite directions, resulting in a rarefied medium formed in the chamber. This leads to the fact that the device sucks air through the discharge channel it is sent to the receiver.

When the compressor equipment in itsworking unit oil sent continuously, it makes more efficient operation of the equipment and increases its durability. To get the compressed air without impurities oil equipment is equipped with a filter system.

Features piston compressors

Piston compressor simpler designand affordable in comparison with screw counterparts. He may have a direct or belt drive. The compressors of the first type are classified into oil-free and oil. A key element of the equipment is a cylinder in which the piston moves. It produces a reciprocating motion, due to the compressed air are created. The piston is powered by a rod, which in turn is connected to the crankshaft. It rotates due to the energy received from the engine and transmitted by direct or belt drive.

When the piston goes down, is filledair cylinder, it passes through the intake valve. In the subsequent step of compressed air is directed to the exhaust valve, and then enters the receiver.

What to look for when choosing a compressor

There are parameters, which are primarily to be taken into consideration when choosing the compressor equipment.

Air pressure. This is one of the most important parameters. It depends on the power unit. The higher the air pressure, the better. Learn about this setting can be from the documents on the compressor.

The duration of continuous operation. Some models are able to work without interruption for hours, others need to rest.

Power. To determine the value requiredfold need in the air all possible users and add 20%. The last point relates to the fact that the compressor should not be operated at maximum load.

As you can see, there are manycompressors. Each device has its own strengths and weaknesses. Get to know their views and considered the key parameters of choice, you can choose the optimal equipment for their own purposes.
